+Introduction
+--------------
 py-yajl is a C-based Python module to interface
 with Yajl (Yet Another JSON Library). While modules like `jsonlib`, 
 `simplejson` and `cjson already exist, py-yajl is intended on providing
 pythonic access to Yajl's extremely fast string and stream parsing 
 facilities.
